Astronomical Calibration Lamps  Astronomical Calibration Lamps are the preferred wavelength calibration solution for most astrophysical spectrographs. In the era of extremely large telescopes, it is often the accuracy of the calibration source that limits the achievable precision. Astronomical spectrographs require precise wavelength calibration sources and a detailed understanding of the associated uncertainties and systematics. Below … Continue reading Astronomical Calibration Lamps
